Python Bluetooth socket accept（）方法不支持'；不接受连接

我目前正在尝试将我的手机与我的Raspberry Pi 3连接，以便将数据从RPI3发送到手机

在《覆盆子》中，我写了以下脚本：

import gobject
import dbus.mainloop.glib
import os
import sys
import time
import bluetooth as bt

dbus.mainloop.glib.DBusGMainLoop(set_as_default=True)

os.system("hciconfig hci0 up")
os.system("hciconfig hci0 piscan")
os.system("hciconfig hci0 iscan")

print "Socket handler ..."
sock_control = bt.BluetoothSocket(bt.L2CAP)
sock_interrupt = bt.BluetoothSocket(bt.L2CAP)

print "Bind ..."
sock_control.bind(("",17))
sock_interrupt.bind(("",19))

print "Listen ..."
sock_control.listen(1)  # Limit of 1 connection
sock_interrupt.listen(1)

print "Waiting for a connection..."
conn_control, conn_info = self.sock_control.accept()
print "Got a connection on the control channel from ", self.conn_info[0]
conn_interrupt, conn_info = self.sock_interrupt.accept()
print "Got a connection on the interrupt channel from " + self.conn_info[0]

while True:
    data = 0x00001e0000000000
    conn_interrupt.send(str(data))
    time.sleep(1)
    data = 0x0000000000000000
    conn_interrupt.send(str(data))
    mainloop = gobject.MainLoop()
    mainloop.run()

当我尝试从手机连接到Raspberry时，我什么也没有得到，程序在.accept（）处被阻止，等待传入连接，即使我已连接

这是我的控制台打印

Socket handler ...
Bind ...
Listen ...
Waiting for a connection...

我试图在

/etc/bluetooth/main.conf

中添加

DisablePlugins=pnat

，但什么也没发生

有什么想法吗
